A pudgy but tough-guy cat recruits Sylvester as his stooge to catch a mouse for his dinner, under the pretense of training Sylvester to be a champion mouser. Sylvester enters a warehouse and runs into the baby kangaroo, Hippety Hopper, and thinks, as usual, that Hippety is a giant mouse that must be fought.
